Electricity WAEC Syllabus

This is the complete Syllabus for this years WAEC examination. Candidates for WAEC GCE (External) and candidates for WAEC SSCE (Internal) are reminded to use this syllabus to prepare for their examination. Click here "WAEC Syllabus" to get the rest of the subjects.

We advise that candidates should be aware of the WAEC examination time table on time in order to prepare very well for the forth coming examination.

The importance of this WAEC Syllabus can never be undermined. Hence, it's advisable to stick to your books as well as this syllabus for highlights and concentration areas. It is also advisable that students becomes aware of the WAEC grading system to know what grade they are exactly aiming for.

Electricity WAEC Syllabus

Below is the WAEC Syllabus for this year; kindly make judicious use of it.

PREAMBLE

This examination syllabus has been evolved from the Senior Secondary
School Electricity curriculum. It is designed to test candidates’
knowledge and understanding of electrical and electronic principles,
maintenance and repair of domestic and industrial equipment and safe
working procedures. The examination syllabus does not replace the
curriculum.

OBJECTIVES

The objective of the syllabus is to test candidates’:

knowledge and understanding of the basic concepts and principles of Basic Electricity/Applied Electricity;

ability to use tools and equipment in the maintenance and repair of electrical/electronic devices;

understanding of the principle of operation and the application of simple electrical/electronic devices;

understanding of safe working procedures and safety precautions in domestic and industrial installation.

EXAMINATION SCHEME

There will be three papers, Papers 1, 2 and 3 all of which must be
taken. Papers 1 and 2 will be a composite paper to be taken at one
sitting.PAPER 1: will consist of fifty multiple-choice objective questions to be answered in 1 hour for 50 marks.PAPER 2: will consist of three sections: Sections A, B and C as follows:Section A will be compulsory for all candidates. It
will consist of four questions out of which candidates will be required
to answer any three.Section B will be for candidates in Ghana only. It
will consist of three questions out of which candidates will be required
to answer two. Section C will be for candidates in
Nigeria, Sierra Leone and The Gambia only. It will also consist of
three questions out of which candidates will be required to answer two.
Thus, candidates will be required to answer five questions in all. The paper will last 1 hour and carry 50 marks.PAPER 3: will be a practical paper of two experiments both of which are to be carried out by candidates in 3 hours for 100 marks.
